To solve this problem, we can use the properties of the binomial distribution and its approximation by the normal distribution when the sample size is large.

So, the approximate probability that fewer than 170 out of 285 randomly selected voters favor a 7-day waiting period is 0.0301 (or 3.01%). I think the third answer choice is wrong as it is clearly marked wrong by the grading system. So, perhaps the answer is not 0.0332 , but rather another answer. It is not clear to me if the right answer is 0.0301 or something else. Please take a look at the attached image.
